The weighted floor crunch feet on bench is a strength exercise that targets the rectus abdominis by adding external resistance to the standard crunch, while the obliques work as synergists to control rotation throughout the movement. Placing your calves on a bench flattens the lumbar spine and removes hip flexor involvement, isolating the abdominal wall more directly than a flat floor crunch. It fits well as a weighted core accessory at the end of a strength session.
Weighted Floor Crunch Feet on Bench: So führst du sie aus
- 1Place a flat bench behind you and lie face-up on the floor, resting your calves across the bench so your hips and knees form roughly 90-degree angles.
- 2Hold a weight plate or dumbbell against your chest with both hands, or extend your arms to hold the weight behind your head if you want a longer moment arm.
- 3Press your lower back into the floor and brace your core before initiating any movement.
- 4Exhale and curl your shoulder blades off the floor by contracting the rectus abdominis, lifting your chest toward your knees in a controlled arc.
- 5Continue rising until your shoulder blades are fully lifted and you feel maximum contraction in your abdominals — your lower back stays in contact with the floor throughout.
- 6Pause briefly at the top, maintaining the brace and keeping the weight stable at your chest or behind your head.
- 7Inhale and lower your shoulder blades back to the floor with control, avoiding any bounce or momentum at the bottom.
- 8Reset the brace before beginning the next repetition and complete all reps in a smooth, deliberate rhythm.
Technik-Tipps
- Keep your chin slightly tucked and your gaze directed toward the ceiling rather than toward your knees — this maintains a neutral neck and reduces strain on the cervical spine.
- Initiate the movement from your sternum pulling toward your hips, not from driving your elbows or swinging the weight forward.
- The range of motion is short — focus on quality of contraction at the top rather than trying to lift as high as possible.
- Select a weight that allows you to complete every rep with a deliberate pause at the top; if you are rushing through the concentric phase, the load is too heavy.
- Press your calves down into the bench lightly throughout the set to anchor your lower body and prevent your hips from rocking.
Häufige Fehler
- Pulling on the weight or swinging it forward to build momentum, which shifts the workload away from the rectus abdominis and onto the hip flexors and neck.
- Lifting the lower back off the floor during the crunch, which shortens the effective range of the abdominals and places unnecessary stress on the lumbar spine.
- Holding your breath throughout the set — failing to exhale on the way up reduces intra-abdominal pressure management and limits how forcefully the abdominals can contract.
- Choosing a weight that is too heavy and compensating by jerking the torso or reducing range of motion, which defeats the purpose of the weighted variation.
- Allowing the calves to slide off the bench, which changes the hip angle and reintroduces hip flexor contribution to the movement.
Häufig gestellte Fragen
What muscles does the weighted floor crunch feet on bench work?
The primary muscle is the rectus abdominis, which runs vertically along the front of the abdomen and is responsible for spinal flexion. The obliques act as synergists, helping to control lateral stability and resist unwanted rotation throughout each repetition.
Why do you put your feet on a bench for floor crunches?
Resting your calves on a bench places your hips and knees at roughly 90-degree angles, which flattens the lumbar spine against the floor and greatly reduces the involvement of the hip flexors. This shifts more of the work directly onto the rectus abdominis compared to a crunch performed with feet flat on the floor.
How heavy should the weight be for a weighted floor crunch?
Start light — a 5 to 10 kg plate is sufficient for most people beginning the weighted variation. The load should allow you to perform every rep with a controlled pause at the top and a slow lowering phase; if your form breaks down before the set ends, reduce the weight.
Is the weighted floor crunch feet on bench good for building visible abs?
Progressive overload through weighted crunches can increase the thickness and definition of the rectus abdominis over time, but visible abs are primarily determined by overall body fat percentage. Adding this exercise to your routine builds the muscle; diet and conditioning determine whether it is visible.
Where should I place the weight — at my chest or behind my head?
Holding the weight at your chest is the safer and more controlled option, especially as you increase load, because it reduces stress on the cervical spine. Holding it behind the head increases the moment arm and makes each rep harder, but only use that position if you can keep your elbows wide and your neck completely relaxed throughout the movement.
